Structural Engineering questions, answered by experts

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

It’s possible to drill into an LVL beam, but you should always avoid it. LVL beams are major structural components of your home, and drilling into them can weaken them and lead to cracking over time. If you need to drill into an LVL beam, consult a structural engineer. They’ll know the bit size, depth, and directionality that’s safe to use when drilling.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.
